Most stuff, sure, but probably not -

> heart rate monitoring

So as someone who is cantering through middle age to a point in life close to where males in my family in older generations have experienced atrial fibrillation and other heart problems, having a heart rate monitor built into my watch that is capable of spotting early signs of this stuff is pretty cool. Having it (crudely) monitor blood oxygen lets me know that for all I snore, I don't seem to have terrible sleep apnea, and I'm considering an upgrade to one that does blood pressure too.

I know this is going to be of limited interest to the young, but these devices becoming more widespread is likely very helpful to an older cohort like myself (I'm 47), making them 'just part of the package' with smart watches puts this sort of health monitoring and information in reach for a lot of people who would otherwise probably not be interested in wearing an ugly medical device, and whose first sign of trouble might be a fibrillation episode or falling asleep at the wheel.

I've got the Aktiia/Hilo band and I'd recommend it if you're wanting to keep vague[0] track of your 24/7[0] blood pressure. Needs calibrating every couple of weeks against the band but that's not an onerous procedure[1][2].

(Probably worth getting a cheapo monitor as a secondary check though - I've got a Renpho bluetooth one.)

[0] It only really takes measurements when you're not "moving" and that can be "running around", "jumping up and down", "typing furiously", etc. which does lead to gaps and only 3-4 measurements every 2 hour slot. Also their app is a bit rubbish and they don't have a decent export story - if you want more than their "daily average → Health", you need BPExtract to OCR the monthly PDF reports (which you have to request by hand, BTW!)

[1] Protip! DO NOT drop the band onto its on/off switch because it's fragile and will BORKEN itself. Mine got stuck in the on position but I've subverted the problem by sticking a magnetic MicroUSB end into the charging point[3] - applying power kicks it into charging mode and removing it leaves it in "ready to use" mode for 5-10 minutes which is more than enough for standard calibrations and testing.

[2] Although their new "BP via the camera and finger" doesn't work AT ALL for me. Almost never gets a reading.

[3] Which I've started doing for all MicroUSB devices because I've somehow managed to snap off 3 MicroUSB ports internally. Shoddy workmanship.

So I have an old fashioned "Salter" inflatable BP cuff unit that takes a few AA batteries, that I take readings on sporadically, and as I am borderline problematic (the diastolic number is usually a little high, systolic is not amazing but could be worse, no meds currently) I'm kinda/sorta looking at something that can keep track a bit more often and less intrusively.

But I was hoping that would be an updated Apple watch, as I have an 8 at the moment that does the other stuff :)

That said I understand that the BP measurements on smart watches are pretty execrable. Thanks for the info!

Yeah, I think that might come in the future but it's probably a patent minefield[0]. That said I think Ringconn mentioned that they were looking at implementing it for their smart rings in the "near future" - who knows?

[0] There's also the "calibration against the smart cuff" step which I'm guessing any solution would need and that's probably a whole other FDA/patent minefield. Also tricky to have to sell a watch model with a required cuff and have to disable the BP functionality on watches that don't have a matched cuff. You can imagine the HN headlines...
